i just got my 2000 A6 about a month ago and noticed some hesitation, so i took it to the dealership yesterday and they called me back today and said there was moisture in the #2 cylinder and i need new plugs and wires, i thought no big deal but then he told me that it would be 375 for parts and labor, so im just wondering how hard is it to change the plugs and wires?

 

What motor?

 

2.8 quattro

 

i mean is everything just under that cover, i havent looked yet

 

or could this just be another problem like the module or a head gasket?

 

Well changing the plugs and coil packs are pretty easy, everything is under the cover. If you do it and order the parts from somewhere like www.ecstuning.com it will be well under $375. The problem is, what kind of moisture is in the cylinder? I would bet it's oil, which would mean changing the valve cover gasket (which is common on 2.8s) and it's easy to do as well. You would need to do that first so you don't foul your new plugs.

 

well the dealership said there was carbon deposit on the plug in the number 2 cylinder. ive changed valve cover gaskets before but it was on a honda so im sure it isnt that simple. i was thinking maybe it was water because the tech kept asking me if i got the car washed before it happened or if i went to a gas station that i dont normally go to.

 

carbon deposit on the plug ????? show me the tools that found that lol, how does it run when is up to temp?? if ok then your mechanic is right ( did they jet wash the engine ) if so just run it till all the water dries out

 

and welcome cough

 

It seems like they are leaning towards a wet spark plug wire causing a misfire. This is easily verifyed at home by spraying the plug wires with water. If you see sparking or the engine runs rough you have a bad plug wire. As for carbon on the plug, thats kinda normal, as one of the byproducts of combustion is carbon.
